live part: conductor or conductive part intended to be energized in normal use, including a neutral conductor but, by convention, not a PEN conductorNOTE 1 Parts, accessible or not, complying with 8.1.4 are not considered to be live parts.NOTE 2 A PEN conductor is a protective earthed neutral conductor combining the functions of both a…
accessible part: part or surface that can be touched by means of test probe B of IEC 61032, and if the part or surface is metal, any conductive part connected to it.NOTE Accessible non-metallic parts with conductive coatings are considered to be accessible metal parts. There are some parts or surfaces in the appliance that…
We know that clause 29.3.2 and clause 21.2 are two separate clauses and they are not very much related, which means that the product being assessed needs to fulfill both clauses if applicable.A reinforced insulation system consisting of three separate layers of insulating material or what could be considered a double insulation system, Each layer…
21.1 Appliances shall have adequate mechanical strength and be constructed to withstand such rough handling that may be expected in normal use.Compliance is checked by applying blows to the appliance in accordance with test Ehb ofIEC 60068-2-75, the spring hammer test.The appliance is rigidly supported and three blows, having an impact energy of 0,5 J,…
non-detachable-part: part that can only be removed or opened with the aid of a tool or a part that fulfils the test of 22.11. The definition of this concept is mainly for the judgment of clause 8 and clause 20, and the judgment of other clauses may also be used. On the appliance, whether any…
clearance: ibanga elifushane emoyeni phakathi kwezingxenye ezimbili ze-conductive noma phakathi kwengxenye ye-conductive kanye ne-indawo efinyelelekayo. Ukuhlanzeka kuwumqondo obaluleke kakhulu. Ukuze siqonde imvume, sidinga ukuphinda sikusho ukuthi akukho lutho oluvalwe ngokuphelele, futhi umoya ungaqhuba nogesi. Lapho i-voltage iphezulu kakhulu, i-current izoqhutshwa emoyeni. Ukushaywa kombani ngesikhathi sokuduma kwezulu kuyisibonelo esivamile sombani oshaya emoyeni. I-voltage yombani iphezulu kakhulu,…
Ukugcizelelwa lapha kuyingxenye yokwakhiwa kwento esebenza ngogesi, engahlangabezana nezidingo zokufakwa okuphindwe kabili noma ukufakwa okuqinisiwe. Ngakho-ke, into esetshenziswayo Yekilasi I futhi izoqukatha ukwakhiwa Kwekilasi II .Isibonelo: Ihhavini eboniswe emfanekisweni ongezansi isebenzisa igobolondo lensimbi kanye nephini lokushintsha lepulasitiki. Uma umsebenzisi ethinta inkinobho yokushintsha, ifindo lenziwe ngezinto ezivikelayo futhi alikwazi ukumiswa. Ukuvikela ngokumelene nokushaqeka kukagesi kungancika kuphela…
Into esetshenziswayo yekilasi II: into esetshenziswayo lapho ukuvikeleka kokushaqeka kukagesi kungancikile insulation eyisisekelo kuphela kodwa lapho kunikezwa khona izinyathelo zokuphepha ezengeziwe, njengokuthi double insulation noma reinforced insulation, akukho ukuhlinzekwa komhlaba ovikelayo noma ukuthembela ezimeni zokufakwa. QAPHELA 1 Isisetshenziswa esinjalo singaba ngolunye kulezi zinhlobo ezilandelayo:– into esetshenziswayo enendawo evalekile ehlala isikhathi eside neqhubekayo yezinto ezivalelayo ezimboza…
umshini kagesi wesigaba I: umshini lapho ukuvikeleka kokushaqeka kukagesi kungancikile ekufakeni izinto eziyisisekelo kuphela kodwa okuhlanganisa nesexwayiso sokuphepha esengeziwe, ngokuthi izingxenye ezifinyelelekayo eziqhutshwayo zixhunywe ku-conductor yomhlaba ovikelayo kuzintambo ezingaguquki zokufakwa ngaleyo ndlela. ukuthi izingxenye ezifinyelelekayo azikwazi ukuba bukhoma uma kwenzeka ukwehluleka kokufakwa okuyisisekeloQAPHELA Lokhu kunikezwa kuhlanganisa i-conductor yomhlaba evikelayo entanjeni yokuhlinzeka. Isibonelo: Ngokuyisisekelo, izinto ezisetshenziswayo…
